Fluorescent spray typography experimental poster

Generate a "Fluorescent Spray Typography Poster".
Theme: [Fill in the theme]
Main Title: [2-6 Chinese characters, suggest splitting or partial cropping]
Subtitle: [Short subtitle, can be left blank]
Core Information: [3-5 short information points, each point controlled within 2-8 words]
Theme Color: [Acid Green / Lake Blue / Fluorescent Orange / High-Brightness Pink / Electric Blue]
Text Contrast Color: [A color that forms a clear contrast with the theme color]

Overall Style: Bright and clean experimental graphic poster, high-brightness paper base, large area of white space, ultra-fine linear font, low-positioned diffused monochrome fluorescent spray, modern editorial design and digital print texture.

The background is rice white, warm white, or light gray-white paper texture, clean and flat, without any texture or photographic background.

The main title uses an ultra-fine, uniform linear font close to an engineering drawing skeleton, with sparse letter spacing and significant scale contrast in font size. Large theme characters are allowed to be close to the edges of the frame or partially cropped, existing like a spatial structure.

The subtitle is horizontally suspended above the frame in a smaller font size.

Place a cloud of fluorescent spray derived from the theme color in the lower-middle part of the frame: the center color is full, and the edges naturally dissipate with a large number of tiny spray dots, particles, and toner of uneven density. Several translucent color mist trails can be dragged out above the spray, creating a slight front-to-back layer for the text.

Text colors use high-saturation warm colors or contrast colors that form a clear contrast with the spray.

Core information is broken into 3-5 groups of short tags, grouped with fine lines, dots, numbering, or minimalist symbols, with sufficient breathing space reserved around each group.

The composition is asymmetric but maintains visual balance, with a clear hierarchy of information and ample white space. Only the edges of the spray are allowed to have graininess and overspray texture.

Forbidden: Heavy shadows, 3D characters, three-dimensional effects, photographic textures, decorative gradients, complex backgrounds, multi-color sprays, crowded layouts, long passages of text, cheap tech-sense.
